Common name: Wrangelia

Wrangelia is a genus of filamentous marine red algae, commonly found in reef aquariums where it can grow as a nuisance algae. It thrives in high nutrient environments and can quickly cover surfaces, outcompeting corals for space and light. Hobbyists often control its growth through manual removal, nutrient export techniques, and introducing algae-eating fish or invertebrates. Wrangelia species are not typically cultivated for aesthetic purposes but understanding their growth patterns is important for maintaining a healthy reef tank.
